This Standard is applicable to valves with pressure ratings not exceeding Class 2500.

The requirements for actuators apply only to pneumatic actuators.

This Standard does not apply to the types of control valves where radioactive service, fire safety testing, or other hazardous service conditions are encountered.

If a standard for hazardous service conflicts with the requirements of this Standard, the standard for hazardous service should take precedence.

NOTE 1 This Standard can be extended to higher pressure ratings by agreement between purchaser and manufacturer.

NOTE 2 The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows:

IEC 60534-4: 2006 Industrial-process control valves-Part 4: Inspection and routine testing (IDT)

The symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/ IEC Guide 21-1.
